Safety apparatus for infant bed

Abstract

A safety apparatus for an infant bed, including a first sensor, for sensing a distance of an infant disposed within the bed from a door thereof, a second sensor, for sensing a distance of an adult disposed outside the bed from the door, a third sensor, for sensing that the door is open, and an alarming gadget, for alarming in case, as sensed by the sensors, the door is open, and the adult's distance is sufficiently large, and the infant's distance is sufficiently small.

What is claimed is: 
     
         1 . A safety apparatus for an infant bed, comprising:
 a first sensor, for sensing a distance of an infant disposed within said bed from a door thereof;   a second sensor, for sensing a distance of an adult disposed outside said bed from said door;   a third sensor, for sensing that said door is open; and   an alarming gadget, for alarming in case, as sensed by said sensors, said door is open, and said adult's distance is sufficiently large, and said infant's distance is sufficiently small.   
     
     
         2 . The safety apparatus according to  claim 1 , wherein said sufficiently large adult's distance and said sufficiently small infant's distance comprise a function of one another. 
     
     
         3 . The safety apparatus according to  claim 1 , further comprising:
 a user interface, for obtaining an age of said infant,   wherein said sufficiently large adult's distance and said sufficiently small infant's distance comprise functions of said infant's age.
